Steve Marinos has truly gone above and beyond in diagnosing and repairing the leak I had under my kitchen sink. He is extremely professional and worked hard to find out what part is damaged in my sink and made sure to have the new parts ordered and installed within a week. He even made sure to use shoe covers inside my home to keep it clean, and asked for paper towels to place under his equipment to make sure it doesn’t damage the counter tops when placed on top. Thank you for all your hard work Steve!

Steve Marinos was professional and kind. He has excellent attention to detail and provided additional information to assist with preventing further issues. He cleared a main line stoppage for my mom, I am extremely happy with his service & will most definitely contact him for any other issues. Thank you Steve! Highly recommended

Tankless Water Heater Flush – Excellent Service This was my first time (in a new home) having my tankless water heater flushed with Infinity, and I wanted to share positive feedback regarding Steve. Steve was punctual, extremely knowledgeable, and arrived about 30 minutes earlier than the expected service window of 8–10 a.m., which was a pleasant surprise as I had anticipated a later arrival. I truly appreciated his timeliness and the time he took to share his knowledge with us. He thoroughly educated us on the O-rings, what to monitor, and what not to be concerned about, which was very helpful and reassuring. I will definitely be requesting Steve for future service visits. Thank you again to Steve for the excellent service. And when he does decide to retire, I know Infinity will miss him dearly.

Steve Marinos and Gene Gallegos from Infinity Plumbing came by to check on our hot water heater which was not working. They came back again and replaced the tank with a brand new hot water heater. Great service, I highly recommend as Steve and Gene were very professional. Steve’s truck looked great too.
